Stacked Multiband Microstrip Antenna

In microstrip antenna research a new trend is found where the researchers improve antenna characteristics by introducing different structures within the antenna geometry. With the development of computational electromagnetic new approaches of analysis has become another branch of activity. This paper presents a design of stacked patch configuration of microstrip multiband antenna, which is suitable for various wireless applications. The proposed wideband stacked antenna is designed on the FR4 substrate, and simulated on Zeland IE3D software. The antenna parameters such as VSWR, return losses, impedance bandwidth and radiation characteristics such as radiation efficiency, gain and radiation patterns have been discussed.
